To all wltom/ if vim/y concern..-

Be it known that I, S'rnriinN McCLnLLAN, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful improvements in Lever Motor-Powers, ofwhich the following is a specification.

My invention is a lever motor-power.

, My invention relates to that class of motorpowers in which the leveris used in connection with a combination of sprocket or frictionratchet-wheels which work on the hub of the gear-wheels and areconnected to oscillating wheels and lever by either a rope, strap, band,or sprocket-chain, and in the further description of the motor i willonly refer to the sprocket-chain; but I do not confine myself to thisalone for transmitting the power from the oscillating wheels to thefriction ratchet or sprocket ratchet wheels and the gear-wheels, but canuse any other of the above-mentioned rope, strap, or band if I find itdesirable to do so.

The following is a full and clear description of the motor applied tothe running-gear of a road-wagon or machine in double form and also adescription of it in single form and. the manner of operating the same.

in the accompanying sheets of drawings. Figure 1 is a perspective viewof my invention. Fig. 2 is a partial top plan view, partly in section.Fig. 2 is a cross-sectional view of Fig. 2 on the line 2 2 Fig. 3 is aside elevation of my invention in modified form. Fig. 4 is a partial topplan view of my invention as shown in Fig. 3. Fig. 5 is a take-up clampfor tightening the sprocket-chain, belt, or band. Fig. 6 is a verticalsectional view of the upper end of the combined lever and guide. Fig. 7is a vertical view of the combined lever, showing a modified form of mydevice for locking either one of the oscillating wheels.

Fig. 1 shows my invention in what I call double form that is, there aretwo exact duplicate sets of the oscillating wheels and of the sprocketratchet-wheels and of the gearwheels and sprocket-chains which arepreferably used in this form when the machine, boat, or wheeled vehicleof any kind is propelled both forward and backward; but I am notconlined to this double form of these parts to accomplish this purpose.In Fig. 3 the motor is shown in single form that is also used andoperated in both directions, if desired.

vlltoferring again to Fig. 1, 1 is a rectangular frame which supportsthe motor mechanism and the axles and their wheels and also the body ofthe road-wagon, tricycle, or other wheeled machine, as only one wheelcould be used on the front axle to support and guide the machine that Ishow in Fig. 1, if desired, -without any material change in the generalconstruction of the framework. The body is not shown in Fig. 1, but maybe of any suitable design. 2 is the front main axle of the wagon, and 2is the rear axle. The front axle is pivoted to cross-bar 1 of the frame1 at its cen ter by king-bolt 3, which is rigidly fixed in axle 2,passing up through the cross-bar 1 in frame 1 and also up through thebottom of the front end of the wagonbody, (not shown,) and passingcrosswise through the head of the king-bolt near its top is a bar 3. Thewheels 4L on the front axle turn loosely on the same, as on ordinarywagons, and may be fitted with ball-bearings. Rear wheels 9011 rear axle2 are provided on their ends of hub F on the inside with aslightly-enlarged part f, which has near its center a lug t cast on it,through which a chisel-pointed ratchet-stem t works, the saidratchet-stem being operated by its coil-spring i (see Fig. 2 saidchisel-point of ratchet-stem r fitting either right or left, parallelwith, and in grooves in the ratchetprojected body 5 of the gear-wheel 5.The said-gear wheel 5 is preferably fitted with ballbearing on axle 2,working loosely on same between the two side bars of the frame 1 and iskept up against the said bars by the supporting-strap 1", fastenedrigidly to said axle 2 between said side bars, and at its outer endriveted or bolted to cross-bar of frame 1 and supports frame 1 and keepsthe edges of holes 1 so that the ratchet-body 5 of gear-wheel 5 passesout through without touching the edges of said holes, thereby notcreating any friction against it. It will be proper to state here thatthis gear-wheel 5 has a duplicate or mate fitting against the oppositeside bar on the other side of strap 1, working on axle 2* the same way,and that the other two gear-wheels with their ratchet sprocket-wheelsand the oscillating wheels hereinafter mentioned each have their exactdi'iplicate wheels working on their axles against the opposite side barthe same as they do. Gear-wheel 6 works on its axle 6", which has ashoulder formed to lit up against its inside end, keeping it upagaiiiist the inside of the frame, and works loosely on its axle 6. Italso has a ratchet-body 6" profooting from its center encircling itsaxle 6,

and on this ratchet-body is fitted sprocket ratchet-wheel 6, which has achisel and ratchetstem 6 passing down through its hub 6 and fitting ingrooves in ratchet-body 6 and operated and held in same by its springpractically the same as the ratchet in the hub of wheel abovedescribed.(SeeFig.2 Gearwheel 7, its axle '7, its ratchet-body 7, itssprocket-wheel '7, ratchet-stemY, and spring, is an exact duplicate ofgear-wheel 6. The gear-wheels 5, 6, and 7 are all situated on theiraxles so that their gear-teeth around their outer rim all mesh with eachother, so that when one is revolved they all revolve. Sprocket-wheel 8on its axle S is so situated in its alinement that it holds thesprocketchain 12 up against the under side of ratchet sprocket-wheel '7and causes it to catch on its sprocket-teeth and operate it, as would beseen if this were not used. When all the gear and oscillating wheelswere used on a direct line, as shown in Fig. 1, the chain 12 would dropaway from the under side of sprocketwheel 7 and would not turn it; butthe oscillating wheels might be placed in a position almost directlyover said s 'irocket-wheel 7", in such a position that this extrasprocketwheel 8 might be dispensed with, so I do not confine myself toits use. Oscillating wheel 9 works on its axle 9, preferably onballbearings, and has a groove of suitable width for the sprocket-chainto fit in. One side of oscillating wheel 9 is cut away at 9, having thesmall friction wheels or rollers 9 and 9 fitted near the points wherethe cut-away portion 9 begins on either side. The take-up clamp 10, usedto tighten the chain, is located in this cut-away part of saidoscillating wheel. Near the upper part of oscillating wheel 9 there areseveral slots 9 in its body for the purpose of allowing the lock-bar 11to drop in that fits in slot 11 of the lever ll and is pivoted in saidslot by a lever or crank handle 11 and is used to lock lever 11" toeither of the oscillating wheels 9 by being thrown into one of the slots9 by a bolt transversely secured to said lever 11", and by a crank orlever 0 a; said bolt may be pushed into holes or slots 9 near the toppart of said oscillating wheels 9, (see modification, Fig. 7,) so I donot confine myself to this lock-bar 11. The hub 11 of the lever 11 alsoworks on the axle 9 of oscillating wheels 9 and fits snugly up againstthe inside of said oscillating wheels 9, keeping them in place upagainst the side frames of the frame 1 and also separating them. Justabove the slot 11 a shoulder 11 is formed around the lever 11", and fromthe upper edge of this shoulder 11 the stem of lever 11 is round. Belowthis shoulder 11, down to its hub 11, it is preferably square if usedwith slot 11 and lock-bar 11, as described above. On the round stem oflever 11, above the shoulder 11, a short cylinder 11 fits snugly, butcan be revolved, and two arms 11 project from its sides near its lowerend. On its upper end notches 11 are formed. Just above the cylinder 11another cylinder 11 fits on the cylinder 11 of lever 11 and has on itslower end projections 11 that fit in notches l1 of cylinder 11 and bindthem together when in use. At the top of cylinder 11- are handles 11that project from its sides. On the arms 11 of cylinder 11 two arms 11are pivoted, and through their outer ends slots l1 are formed, andthrough these slots a crossbar 3 in the top of king-bolt 3 passes. Eachend of the sprocket-chains 12 is fastened to the ends of the take-ups10. Rollers 9 on oscillating wheel 9 then pass over the top of theratchet sprocket-wheel 6, that works on the ratchet-body 6 of thegear-wheel 6, then returns back under the ratchet sprocketwheel 7, thatworks on the ratchet-bod y 7 of gearwheel 7, thence up over the sprocketguidewheel 8, and down under the lower edge of oscillating wheels 9 tothe lower end of takeup 10 at friction-wheels 9.

To operate m y machine, the operator would take his seat, situated onthe body of the wagon just rearward from the lever, (not shown indrawing) and then if he wanted to move the machine forward he wouldfirst, by the use of the lever or crank-handle 11, throw the lock-bar 11into one of the slots 9 in the oscillating wheel 9, that is on theright-hand side of the lever 11". This looks lever 11 to the saidright-hand oscillating wheel'9. Then by pushing and pulling on saidhandles 11 backward and forward, moving the chain 12, which in turnmoves the ratchet sprocketwheels on the gear-wheels 6 and 7, which byreason of their meshing together in their cogrims and with gear-wheels 5cause it (cogwheel 5) to turn, and its connection with the right-handwheel a by its ratehet forces it to turn, which moves the wagon forward.The ratchet-plungers in the ratchet sprocketwheels on gear 6 and 7,being set reverse from each other, the one on gear 7 looking as thelever is pushed forward, thereby causing gear-wheels 7 to turn forward,and it in turn by its cog connection with gear-wheel 6 making it (thesaid gear-wheel 6) turn backward, and it by its cog connection withgear-wheel 5 causing the said gear 5 to turn forward, which wheel atbeing locked to the said gearwheel 5 by its ratchet connections travelswith it. The backward movement of the wagon is gotten by throwinglock-bar 11 to the left into one of the slots in the left-handoscillating wheel 9, the ratchets in gear-wheel 5, 6, and 7 being set inthe opposite direction to the one just described for the forward motion.By the operator moving the lever just as he did before backward andforward he propels the wagon backward, and to guide the machine or wagonhe simply turns the handles 11, which in turn turns both the cylinders11 and 11, which move the arms 11 veasev m which turn the front axle 2by reason of their connection with the king-bolt 3, cross-bar 3,provided with shoulders 3", so that the operator can at the same time heis operating the machine either backward or forward guide the same bythe same lever.

it will be seen by the peculiar arrangement of my motor-power that thereis absolutely no dead-center to overcome, as the machine will moveinstantly either forward or backward by the slightest movement of thelever. The only lost motion in it would be what is usually lost in asprocket chain or belt connecting or running power.

The backward movement of my machine can be used when going downgrade abrake, and the arrangement of the ratchet sprocket-wheels on gears 6 and7 to either turn with them or stand still by their ratchetplungerslipping over the grooves or teeth of the said ratchet-heads on the saidgears 6 and 7, so that the machine when it has momentum enough to runwithout the operator working the lever going downgrade the sprocketwheels and chain and oscillating wheels and lever can stand perfectlystill, unless he should want to use the backward motion just as a brake.This is a valuable point in my machine, as it would be objectionable tohave them turning when not needed. The gear-wheels 5", (5, and 7 wouldturn with the wheel 4: on the right-hand side if the machine were stillset for the forward motion; but the ratchet wheels on 6 and 7, thechain, and the oscillating wheels would stand still, and on the lefthand all the wheels except the wagonwheels 4 and t would stand still, asthe ratchet in the hub of left-hand wheel 4: would allow it to turnforward without its turning its connecting gear-Wheels 5, as its ratchetis set to slip when going forward.

The gear-wheel 5" can be used either larger or smaller than the gears 6and 7, thereby either increasing the speed of the machine or decreasingif more power is needed.

Fig. 3 shows my machine as an exact duplicate of one side section ofFig. 1 with the gear-wheels 5 left off, with the exception that an extraratchetsocket would project from the outside of the center ofgear-wheels 6, and the ratchet-body on the ratchet-wheel side can extendout longer, so that wheels 4, as shown in Fig. 1, could be used on thempractically the same as they are used in Fig. 1, but could not be usedin the backward movement of the machine unless the ratchets in ratchetsprocket-wheels bn gears 6 and 7 were reversed.

The motor in the single shape would be used when the reverse or backwardmotion was not often needed.
